Purchased in Hakone, Japan in 1989.

This box was signed by all who attended the 1st JPCP (Japanese Puzzle Collectors Party) in Tokyo 1989.

The money for its purchase was loaned by Akio Kamei. After the Party it was packed for mailing back to England and left with Nob Yoshigahara. Nob secretly removed the box from the parcel and with many friends drew pictures and messages all around the interior in such a way that they would only be revealed step by step as the box was opened.
